Planets start as planetismals then accrete into larger and larger planets, Terrestrial planets accrete rock/metal from surrending planetary nebula, while Jovian planets accrete frozen H compounds beyond the frost line (between Mars and Jupiter). Everything in the solar system is getting larger, even the Sun.
